TYPE-WRITING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 676,184, dated June 11, 1901.

Original application filed November 26, 1898, Serial No. 697,505. Divided and this application filed April 3,1899. Serial Nil-711,593. (No model.)

To all whcmt it may concern:

Be it known that I, EUGENE FITCH, a citizen of the United States, and a resident of Astoria, city of New York, in the county of Queens and State of New York, have in vented certain new and useful Improvements in Type-Writing Machines, of which the following is a ing machines in general, and more especially to that class of type-writing machines in which the matter written is in full view of the operator during the progress of writing, one object of the invention being the provision of a comparatively simple, practical, and effective visible-writing machine.

Another objectis the provision of a simple and effective case-shift mechanism and means for locking the same in shifted position and for instantly releasing it when desired.

Another .object of the invent-ion is to provide for the spacing apart of lines at different intervals without adjustment of the linespacing mechanism.

Another object of the invention is to regslate the right and left hand margins and to adjust the stops therefor expeditiously to new positions and to firmlyhold them in such positions, and other objects as will hereinafter fully appear.

To these ends the invention includes features of construction and combinations of devices hereinafter described,and more particularly pointed out in the appended claims.

The preferred form of the invention is illustrated in the accompanying drawings, forming part of this specification, in which-- Figure 1 is a plan view of the said form of the invention. Fig. 2 is a right-hand side elevation of the machine. Fig.3 is a central vertical sectional view from front to back. Fig. 4 is a rear elevation, some parts being omitted and others being broken away or in section. Fig. 5 is a plan View, with some parts omitted, of the rear partof the machine below the plane indicated by the line X X in Fig. 2. Fig. 6 is a side elevation of the platen shift mechanism. Fig. 7 is a front view of the platen-shift keys and locks. Fig. 8 is a perspective view of spring-catches for locking the platen in its shifted position. Fig. 9 is a perspective view of a margin-stop. Fig. 10 is a view showing the inking-roller and parts connected therewith.

In the various views the same part will be referred to by the same reference numeral or with the frame 3 and are connected withthe frame 2 by means ofscrews 8, which pass through the feet 7 and whose threaded ends engage with threaded holes in the uprights 4, as shown in Fig. 4. Sheet-metal or hard-rubber plates 9 are sprung into grooves 10 in the upper side of frame 2 and the under side of frame 3, thus inclosing the space between these two frames.

The type-bars 11 are formed in two parts 12 13, which are hinged together at 14 in a direction at rightaugles to the axis 15 on which the type-bar is pivoted. The axis 15 is a straight shaft or bar pivoted or otherwise secured in brackets 16, secured to the top of frame or plate 3. Each piece 12 is provided with an enlarged circular end 17, which is formed with an open slot 18, whose bottom is formed to fit the round shaft 15. Each end 17 is also provided with a notch 19, which fits and receives the end 20 of the corresponding key-lever 21. Inasmuch as the slots 18 and 19 open in opposite directions and the round- 5 ed ends 20 of the key-levers engage the slots or notches 19 opposite the fulcrum orpivotrod 15, it results that each type-bar is locked carrier 55 with ratchet-wheels 69 70, and the end pieces 56 57 are provided with levers 71 72, pivoted thereto at 73 74. The lever 71 is provided with a pawl 75, pivoted thereto at 76 and adapted to engage with and rotate the ratchet 69 and platen 38. Normally the pawl is pressed toward the ratchet by a spring 77, secured to the end piece 56 by a screw 78 and bearing against the rear side of the pawl, and is normally held out of engagement with the ratchet 69 by means of the pin 79 projecting outwardly from the end piece 56 and engaging with the beveled face 80 of the pawlpiece, since the spring 81, which holds the lever 71 in its upper or normal position, is of a strength sufficient to overcome the resistance offered by the other parts to such action. The spring 81 has one end secured to the lever 71 by a screw 82 and has its other end bearing on the top of a screw 83, which projects from the end piece 56 through a curved slot 84: in the lever 71. The reaction of spring 81 against the screw or stop 83 tends to lift the lever 71. The center of the arc of slot 84 is the pivot 73, as will be understood. A spring-detent 85, secured at one end to the end piece 56, acts to prevent accidental rotation of the ratchet 69 and platen 38, while it permits of their rotation in either direction at will by means of force applied to either hand-wheel 67 68. A similar detent may be used at the other end of the platen. The end piece 56 is provided with one or more holes 86 opposite the slot 84 for the reception of a pin or stop 86 for engagement with the upper end of the slot 84; for the purpose of limiting the rotation of the platen to one or more spaces corresponding to the distance between the teeth of ratchet-wheel 69, according to the number of holes 86 and that one of them in which the pin may be placed. The end of lever 71 is formed into a ring for convenience of getting a hold upon it to depress it for line-spacing. The lever 72 is or may be connected with its ratchet 70 in precisely the same Way to rotate it and the platen for line-spacing. If the slots. 81 be of sufficient length to permit of at least two dilferent widths of line-spacing, the line-space lever at one end may be set to give, say, one width and the line-space-lever regulator at the other end of the platen may be set to give a different width of line-spacing, whence it results that an operator may write matter of either or both of such widths of spacing without having to set or reset a line-space regulator. This feature is of great convenience in writing briefs and the like, where many quotations are made and are put in half-space or solid, while the remainder is put in with wider spacing between the lines.

The paper is held against the platen by means of a roller 87. I prefer to journal the roller 87 in lugs or projections on the paperguide 88, which is pivoted to the ends 56 57 at 89. One or more springs 90 between said guide 88 and one of the rods 58 serves to press the roller yieldingly against the platen. A paper-holder is provided for coaction with the platen above the line of printing or writing, said holder consisting of a small rod 91, borne by pivoted arms 92 93 at the ends of the platen or platen-carrier. The arms 92 93 are provided with extensions or handles 94 95, whereby the frame formed by said arms, journaled shaft 59, and rod 91 may be rocked to move the rod away from the surface of the platen, as in inserting paper. A spring 96, coiled about the rod 59, has one end connected with the rod 59 and the other secured to some fixed part of the platen-carrier, as end 56, and tends to keep the said shaft or rod 59, arms 92 93, and rod 91 in the positions shown in Figs. 1, 2, and 3.

The end pieces 56 57 of the platen-carrier may be provided with open-ended oblique slots 97 for the reception of the pivot rod or shaft 66, thus allowing of the ready removal of the platen from the carrier. It will be noted that detent 85 tends to prevent removal of the platen, being between the bearing in slot 97 and the open end of the slot.

The carriage is provided with a toothed bar 98, fast to the top of frame 47, which bar is provided withlongitudinal grooves 99 at its front and rear sides. Upon this bar 98 are mounted two margin-regulators or carriagestops 100 101, one of which is shown in perspective in Fig. 9. These steps are each formed of two parallel arms 102, united at one end by a cross-tie 103, which is adapted to enter or fit in between the teeth of the bar 98, as indicated in dotted lines in Fig. 4. The arms 102 are provided with inwardlyprojecting pins 101 for engagement with the grooves 99, thus providing pivots about which the stops 100 101 are swung to engage and disengage them from the teeth of the bar 98 when adjusting them along the same. The stops 100 101 respectively coact with fixed abutments 105 106 respectively affixed to the tops of the end standards 5. (Shown in Fig. 4:.) The stop 101 also carries the bell-trip 107, which is pivoted at 108 to an arm 109, rigidly attached to the stop 101. A pin 110 on the arm 109 acts as a stop to limit the motion of the trip 107 in one direction. The bell 111 is carried by an arm or bracket 112 on one of the uprights 5, and the bell-hammer 113 is pivoted at 11 1 to an arm or branch of bracket 112 and is provided with an arm 115 for coaction with the trip 107, as will be understood.

The letter-feed mechanism will now be described.

The screws 121 pass loosely through the slots 122 123 and engage with threaded holes in plate 116, (and lower bar of the carriage 47 Preferably the slot of the screw which passes through it, thus permitting of the retractionof the carriage toward the right without having to disengage the rack from the escapernent-pavvls, or vice versa. A spring 124, fast at one end to the plate 116 and at the-other end to a pin on the plate 119, actsto draw the tooth 1:210 toward the rack 1'18 and also to slide the plate 119 toward the left hand side of the machine whenever-the tooth 12 0 is released frornen- The rack-bar 118 is borne byarms 125, which also carry the universal bar 126, and is normally lifted The 1 plate 119 has a limited movement relatively are pivoted at 127 in brackets 128-, fast to the top 01: plate 3.

Also the other-end .o f spring 1'32 is preferably connected with the sheave 135 on wheel 131 by 111631118011 .a cord A strut or brace 137 is shown 'or-strap 136. between the rods '6, the function of which is j to prevent bend-ing ondistortion of the same. 1

This strut is perforated at 138 to allow thei spring 132 to pass freely through it.

The platen-shifting mechanism will nextl described, and the rod 6'5, .on whichthe roller? "64 traverses during the operation .of thema-i chine.

The rod '65 is borne by arms 139 140, fast on a shaft 141, which is journaled ina brackets 142, rising from the t-op'ot frame 3. Z

An ex'tensi'on 143 of thearm 140 is-connected jwith theV shaped lever 144 by a pitmanqorf link 145, Fig. 6, which is pivoted to the-end;

of the arm 143 and at orznear the point of the Vet lever 144. The lever 144 is pivoted 13.13%

146 to a. bracket 147, rising from thetop rfirame:

'orplate 3. One branch-of the 1ever 144.'is;pro-

vided with the cap-key 148 and the other branch is provided with. "the figure-key 149. The :arms 139 140 are normally held in a central position by the weight of the platenc'a-rrier, platen, and appurtenances and the springs 150 and stops 151 for the springs. The strength of the springs 1.5.0 is such that they lift the .platen-carrierand the parts supported thereby until the springs 150 are stopped by the stops 151. This brings the platen in such relation to the typeon the type- .bars that the middle types 19 thereof .coact-wi-th :the platen. When the key 14.9 is depressed, the rod 165 is moved'downwardand carries with it the springs 1.50, as in Fig. 6. This allows the platen-carrierand parts carried thereby to fall or move downward, and thus brings the platen in such position that the lower types a on the type-bars coact with the platen to print the figures and other-characters shown at the front of the keys .24. When the key 148 is depressed, the parts take the position shown in Fig. 6 in dotted lines, (except that springs .150 rest against stops 151$ and the platen-carrier and parts supported thereby are raised into position to coact with the 11pper types a on the type-liars, thus printing capital letters and such other characters as may he em ployed in addition thereto .on such upper ends of the type-(blocks. The bracket 147 is provided with two legs or rears 1'52 153., :and these are provided with;adjzustablestops 154 155 for :the lever 144.

In order to release the lever 144 when it has been locked, as above described, it is only necessary to push down the depressed key 148 or 149, whereupon the spring-arm carrying the corresponding catch will be freed from the lever 144 and will spring out and carry its catch out of the path of the lever 144, which can then be returned when released to normal position through the power of springs 150 or the weight of the platen-carrier and parts supported thereby.

The operation of the foregoing devices has been given in substance during the description of the parts and need not be repeated.

For the purpose of adapting the type-writer to the use of bookkeepers or others who have to make out statements or bills there is provided adding mechanism which can be thrown out of and into operation at Will.
